Adjunctive PCSK9 Inhibitor Evolocumab in the Prevention of Early Neurological Deterioration in Non-cardiogenic Acute Ischemic Stroke: A Multicenter, Prospective, Randomized, Open-Label, Clinical Trial.

Background: Early neurological deterioration (END) is associated with a poor prognosis in acute ischemic stroke (AIS). Effectively lowering low-density lipoprotein cholesterol (LDL-C) can improve the stability of atherosclerotic plaque and reduce post-stroke inflammation, which may be an effective means to lower the incidence of END. The objective of this study was to determine the preventive effects of evolocumab on END in patients with non-cardiogenic AIS.

Design Principles for Gradient Porous Carbon on Aqueous Zinc-Ion Hybrid Capacitors: A Combined Molecular Dynamic and Machine Learning Study.

Gradient porous carbon has become a potential electrode material for energy storage devices, including the aqueous zinc-ion hybrid capacitor (ZIHC). Compared with the sufficient studies on the fabrication of ZIHCs with high electrochemical performance, there is still lack of in-depth understanding of the underlying mechanisms of gradient porous structure for energy storage, especially the synergistic effect of ultramicropores (<1 nm) and micropores (1-2 nm). Here, we report a design principle for the gradient porous carbon structure used for ZIHC based on the data-mining machine learning (ML) method.

Schiff Base-Mediated Dual Active Site Catalyst for Efficient N-Formylation of Amines with CO.

Using CO as the C1 source for N-formylation of amine is a crucial energy-storage pathway to address the greenhouse effect while generating high-value-added chemicals but is limited by the activation of inert molecules. Herein, a dual active site catalyst with high CO activation and dihydrogen dissociation capacity was fabricated by incorporating a Schiff base and Au nanoparticles (NPs) on silicon dioxide (SiO). The modification of the Schiff base not only provides an alkaline environment for CO absorption but also stabilizes Au NPs in a small and highly dispersed state, which regulates the electronic density of the metal for excellent H cleavage.

"Alkyl-Substituted Phenoxy" Spacer Strategy: Antiaggregated and Highly Soluble Zinc Phthalocyanines for Color Films.

A series of zinc phthalocyanine derivatives (ZnPcs) were designed by introducing different volumes of steric hindrance groups (chlorine atom, n-propyloxy, isopropyloxy, n-butoxy, isobutoxy, -butoxy, 2,4-di--butylphenoxy, 2,4-di--pentylphenoxy) on the peripheral and nonperipheral positions of phthalocyanine. Density functional theory (DFT) calculations presented that the substitution of sterically hindered 2,4-di--butylphenoxy or 2,4-di--pentylphenoxy on the peripheral positions effectively reduced the aggregation of ZnPcs, improving the solubility of ZnPcs, and the simultaneous substitution on the peripheral and nonperipheral positions could achieve ZnPcs with different colors. From the calculation results, six low-aggregation ZnPcs were synthesized for the first time.
